Grace and peace in the Lord to all pious Christians and friends in Christ! To these good people, He Franciscum, who are coming to Germany from distant lands, I ask that every one of you, whom he is going to visit, have commanded and appear helpful to him.
For we are almost overloaded here in Wittenberg, and more than our poverty is able to provide, are visited by many both expelled and otherwise good people, who would like to study, for help, and do not find so much here, as they, according to the great name, would have provided, that more arid surrounding neighbors, who are spared with such daily burden, should also do help and tax. Who knows how God will protect us and greet us, and what He may want to make of such people?
There were also some strangers among the people of Israel, who became better than many others of Israel, such as the tenth leper in the Gospel of Luke 17, and the centurion of Capernaum. Therefore we must think that for Christ's sake we should be justly favorable to such people, regardless of the fact that they are sometimes lost to evil people, whom the pious should not reward.
Let each one do what he knows in his conscience. Hiemit GOtt befohlen, Amen. Friday after Cantate [May 24] Anno 1538.
